This expanded stainless steel, overhead dock-door system is designed to ventilate any commercial facility, while preventing the problems that occur when overhead loading dock doors are left open. This door eliminates entrance by unauthorized people, birds and rodents. It also acts as a deterrent for employee theft. This provides security and peace of mind for your facilities.
The Expanded Metal Overhead Security Door operates in its own track, as the preferred method, or is added to the existing overhead door’s track system. Using the existing door’s lower vertical track, we add a track switch mechanism at the top of the opening, a second set of upper tracks, and a sectional expanded metal stainless steel door. The unique track switch design allows for the independent use of this door and the existing overhead door, without manual intervention. A dual track system is also available. This configuration allows the user to lower our door and vary the amount of ventilation with the main one for security applications. It utilizes 3/4 inch, 20 gauge, flattened, expanded 304 stainless steel.
The Expanded Metal Overhead Door System can be used in new construction or retrofitted into any existing high lift, vertical lift and standard lift loading dock doors using the track switch mechanism. It utilizes the same vertical track as the existing door for a tight seal against the door header. The track switch is available for 2” or 3” track applications and has a lifetime warranty.
Another application approach for high lift, vertical lift and standard lift loading dock doors is to install a second (dual) track behind the existing door’s track. Galvanized steel, reverse-angle side plates close any gaps created by the second track. Brush seal can be used to eliminate gaps on the sides and across the top of the Expanded Metal Door. The advantage of the dual track is the ability of the user to place the Expanded Metal Door in the down position and place the existing door at any level within the opening, thereby regulating the amount of airflow allowed into the facility.
